MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary (tonespace) and shared library (tonespace.so) from mucoder.net, which is the official vendor website for this product (the url= field matches the download host). The binary is executed directly and the .so is installed to /usr/lib. While mucoder.net appears to be the legitimate upstream vendor site rather than a random personal host, it is not a major trusted platform (GitHub releases, etc.), and there is no source code — only prebuilt binaries with a sha256 checksum. The checksum provides integrity but not authenticity. This is a classic medium-risk pattern: prebuilt closed-source binaries from a small vendor site with no way to verify the build chain. The risk is real but not evidence of active malice.

Triggered rules

MEDIUM source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
